PMV50A600 - 3PH SYSTEM MULTI PROTECTION RELAY 600V

Why Choose the PMV50A600?

The Lovato PMV50A600 voltage monitoring relay safeguards three-phase systems without neutral by supervising minimum and maximum AC voltage, phase loss and incorrect phase sequence. Self powered and rated for 600VAC at 50/60Hz, this unit provides a single relay output and simple setup via potentiometers. SKU PMV50A600 delivers reliable protection across demanding industrial and commercial installations.

Engineered for longevity, the PMV50 features 8 A Ith (IEC) contacts and a mechanical life of 30,000,000 cycles, with 6 kV impulse withstand for harsh environments. Operating from -20 to +60 °C and weighing 130 g, it installs securely with 0.8 Nm terminal torque. Conforms to IEC/EN 60255-5, 61000-6-2, 61000-6-3, UL 508 and CSA C22.2 n° 14, supporting rigorous UK and global panel standards.
